12,121 PointsCan not get past robots.swift, need help
We as a class can not get past this point. We have tried many options. Please help.
class Point {
var x: Int
var y: Int
init(x: Int, y: Int) {
self.x = x
self.y = y
}
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(_ direction: String) {
print("Do nothing! I'm a machine!")
}
}
// Enter your code below

8,386 PointsHi Jarrett,
In this challenge, you need to create a new class, Robot, that is a subclass of Machine.
All the subclass needs to contain is a method called "move" that overrides the superclass method of the same name.
The move method takes an argument, direction. We will use the value from this argument to move the location (x or y coordinate) which is a class property defined in the Machine superclass.
Here is the code:
class Point {
var x: Int
var y: Int
init(x: Int, y: Int) {
self.x = x
self.y = y
}
}
class Machine {
var location: Point
init() {
self.location = Point(x: 0, y: 0)
}
func move(_ direction: String) {
print("Do nothing! I\'m a machine!")
}
}
// Enter your code below
class Robot: Machine {
override func move(_ direction: String) {
switch direction {
case "Up": self.location.y += 1
case "Down": self.location.y -= 1
case "Left": self.location.x -= 1
case "Right": self.location.x += 1
default: break
}
}
}
